Indeed. I'm running gentoo on my main box for a few months now.

Regarding kernel patches, with just a little grepping in the portage 
tree I was able to glean the following info...


source			latency-related info
------- 		---------------------
ck-sources		"in general his kernels are known to be VERY 
			 low latency." 
			 doesn't say what patches are contained, but
			 based on notes in other sources, I guess
			 LL, PE, and O(1)

gaming-sources		ebuild contains a URL of a page that tells all:
			http://members.optusnet.com.au/ckolivas/kernel/
			... at which you can see it contains LL, PE, 
			and O(1) among other things.
			Also read the FAQ, it mentions some notable bugs
			e.g. hdparm is broken at least with gaming-sources
			for 2.4.21:
			http://members.optusnet.com.au/ckolivas/kernel/#faq


gentoo-sources		"Based heavily on ck-sources-2.4.20-r2..."
			contains LL,PE,O(1)

gs-sources  		contains LL, PE

gentoo-hardened		- ck7-base (O(1), preempt, low latency)

mm-sources		This is for 2.5/2.6 kernels, which I have not
			really paid attention to. Contains some patches
			from Andrew Morton.

wolf-sources		"replaced:LowLatency in favor of lowlatency 
			 fixes from latest -AA"


Note that you still have to pay attention to configuration options:
e.g. if you don't enable lowlatency and preemptible during kernel
config, the patches might as well not be there :-)
